Goto is useful in breaking out of a nested loop and when there is a
clean-up section of a function that should be executed for various
error conditions.

In another newsgroup I once asked "who needs GOTO" and got some good
answers -- the thread can be found by Googling 'beliavsky at aol.com
"explicit GOTO"'. Goto's are less dangerous when they are in the
forward direction, to code appearing later.
